I like the sound of the V6, but I like the sound of many types of engines. For displacement and its technology the Offy 4 Cyl they ran at Indy was one awesome sounding engine. The stock exhaust note on the Mustang does improve with age, as I can testify based on the 53K mile. unit that I traded in for the 14. However, contrary to what someone said earlier, I have heard stock mufflers paired with off road x/h pipes and its like the same notes amplified. I think that is the route I will take as it adds volume and hp.
